FCC REQUIREMENTS
NOTE: This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions: (1) this device may not cause
harmful interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
This equipment generates, uses, and can radiate radio frequency energy. If not installed and
used in accordance with the instructions, may cause harmful interference to radio
communications.
However, there is no guarantee that interference will not occur in a particular installation. If
this equipment does not cause harmful interference to radio or television reception, which can
FCC WARNING
This equipment generates or uses radio frequency energy. Changes or modifications to this
equipment may cause harmful interference unless the modifications are expressly approved in
the instruction manual. The user could lose the authority to operate this equipment if an
unauthorized change or modification is made
be determined by turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
• Re-orient or relocate the receiving antenna
• Increase the separation between the equipment and the receiver
• Connect the equipment to an outlet on a circuit that is different from that to which the
receiver is connected.
Replacing battery
WARNING!
Only qualified service personnel may install this equipment. The instructions in this manual
are intended for use by qualified service personnel only.
Only qualified persons should service the system.
The installation and service of this hardware is to be performed only by service personnel
having appropriate training and experience necessary to be aware of hazards to which they
are exposed in performing a task and of measures to minimize the danger to themselves or
other persons. Electrical shock hazards from the telecommunication network and AC mains
are possible with this equipment. To minimize risk to service personnel and users, the system
must be connected to an outlet with a third-wire Earth.
Service personnel must be alert to the possibility of high leakage currents becoming available
on metal system surfaces during power line fault events near network lines.
These leakage currents normally safely flow to Protective Earth via the power cord.
Therefore, it is mandatory that connection to an earthed outlet is performed first and removed
last when cabling to the unit. Specifically, operations requiring the unit to be powered down
must have the network connections (exchange lines) removed first.
Intrinsic safety
Do not install the unit in conditions where there is a danger of electrically ignited explosions.
Exposure to sunlight, heat and moisture
!
CAUTION
:
RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE.
DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS
Do not expose the unit to direct sunlight for long periods. Keep away from excessive heat and
moisture.
Spare parts and accessories
Use only approved spare parts and accessories. The operation of non-approved parts cannot
be guaranteed and may even cause damage.

2. ISL024DB1
The ISL024DB1 transceiver is a narrowband radio designed for license-free operation in
900MHz ISM band.
The ISL024DB1 has a fixed 1mW of output power for use in the USA and Canada 902MHz
– 928MHz ISM bands.
This is a half-duplex wireless data transceiver which is integrated with an ultra speed MCU
and a powerful RF chip.
A software application is offered so that users can modify the settings of the module. Its slim
size, and ultra long transmission distance makes itself the most popular selection of many
applications in different fields.
3. Theory of operation
3.1 Network Topologies
Topology refers to the shape of a network or the network’s layout. How different nodes
communicate with each other is determined by the network topology. The ISL024DB1
support a point-to-point and a point-to-multipoint network topology.
3.2 Point-To-Point
A point-to-point network consists of only two radios, one configured as a receiver and one
configured as a transmitter. Sometimes referred to as a wireless bridge, a point-to-point link
replaces a single communications cable.

Receiver
3.3 Point-to -Multipoint
Point-to-multipoint systems have one base station (receiver) that controls all communications
with all of the other wireless nodes in the network. This allows for the creation of a wireless
network consisting of multiple nodes. In a point-to-multipoint network the receiver would
typically be set up as the access point and would be configured to receive data. The other
nodes would be set up as transmitters.
There is a limit of 60 transmitters that can be configured in a point-to-multipoint network, but
all radios would share the same bandwidth over the RF, so as more nodes were added care
should be taken when transmitting data to prevent collisions.
